I went to CSULB. I was an uncool nerd. Luckily, I have evolved into the coolest 50+ year old ever. 
In high school, I was a decent student, but math was my weak point.
For kicks, I have literally just pulled out my high school transcript. Freshman year, I got a C in Algebra. So I took Algebra Concepts and got a B. Then I did Algebra again as a sophomore, and got a D first semester, and an F second semester.
I really should have just stuck with Algebra as a Freshman. As a second semester Junior, I took Algebra again and got a B.
I took Geometry as a senior. I got a D+ and a C.
I attended CC. I was put on academic probation because I ditched too many classes and went to the beach. Itâs a good thing that happened, because I finally got my act together. In college, I struggled to complete my required math class. I took a class called Liberal Studies math, and the only thing I remember is that we learned how to recombine the letters in the word Australia. I took it C/NC and passed! 
The next year, the college eliminated that course as valid for the degree. So phew! Good thing I took it when I did.
I only applied to one college in order to graduate, but before that, I earned credits at a variety of CSUs (CSUN, CSUF, CSUDH), including a semester abroad that changed my life profoundly. Finally, after 6 years, I was the proud recipient of a BA.
Iâm kind of amazed that I am even on College Confidential, tbh 
Edit: I never took an ACT or SAT. And when I graduated, my GPA was only 3.0 because of my math grades. If I am honest, I would have gone completely ballistic with my kids if they did what I did, either in high school or in college.
